**Article Title: **HPV induced R-loop formation represses innate immune gene expression while activating DNA damage repair pathways

**Journal: **PLOS Pathogens

**doi: **10.1371/journal.ppat.1012454

**Figure Legend Snippet:**(A) Major pathways whose expression is dependent on R-loops present only in CIN 612 cells as determined by RNase H1 overexpression. Pathway analysis was performed using the Hallmark database in Shiny GO 0.80 of R-loop regulated genes that contain R-loops unique to the CIN 612 cells. (B) Innate immune response genes whose expression is regulated by R-loops that are present only in CIN 612 cells. Fold changes are normalized to the mRNA counts in normal keratinocytes (n = 2). Linkages to H3K36me3 and γH2AX histones are shown on the right.

**Techniques Used: **Expressing, Over Expression

**Figure Legend Snippet:**(A) mRNA levels of genes γH2AX that are negative or positive in HFKs (left) and CIN 612 (right) cells. The red line represents the mean. The error bars are SEM (p<0.05, *; p<0.0001, ****). (B) Venn diagrams of the genes containing γH2AX and R-loop peaks (MACS) overlapping between the HFKs (left) and CIN 612 (right) cells (n = 2). Genes containing γH2AX peaks (red), R-loop peaks (green), and both (brown). P-values represent that the overlap between genic marks is above or below that expected from random distribution. RF represents representation factors. RF values greater than 1 suggest more overlap than expected from random distribution, while RF values less than 1 imply less overlap. (C) Venn diagrams of the genes containing γH2AX, H3K36me3, and R-loops in CIN 612 cells (left) and the GO biological processes pathway analysis of these genes (right). (D) A table showing DNA repair and metabolism genes that are differentially expressed in CIN 612 cells with corresponding marks of R-loops, γH2AX, and H3K36me3, which are present on these genes only in the precancerous cells.

**Article Title: **BRCA1 and 53BP1 Regulate Reprogramming Efficiency by Mediating DNA Repair Pathway Choice at Replication-associated Double-Strand Breaks

**Journal: **Cell reports

**doi: **10.1016/j.celrep.2024.114006

**Figure Legend Snippet:**A) Illustration of the BRCA1 polypeptide and a simplified interaction engagements. The C-terminal BRCT domain of BRCA1 interacts in a mutually exclusive manner with the phosphorylated isoforms of ABRAXAS, BACH1, or CtIP to form distinct BRCA1 complexes. In addition, BRCA1 harbors a coiled-coil motif that mediates its interaction with PALB2 and the recruitment of BRCA2 and RAD51 to sites of DNA damage. The mutant mouse alleles used in this study: Brca1tr encodes a pathogenic truncating mutation, denoted with a red arrow, that eliminates the BRCT domains. AbraxasS404A, Bach1S994A and CtipS326A each encode a missense mutation that eliminates a phosphorylation site necessary for the interaction of its protein product with the BRCT domain of BRCA1. B) Morphology and size of E13.5 embryos. The difference between wt ctrl and AABBCC was evaluated with an unpaired two-tailed student’s t-test.; wt ctrl n = 9, AABB n = 5, BBCC n = 4, AACC n = 3, AABBCC n = 3. C) Rad51 foci immunofluorescence and quantification in induced pluripotent stem (iPS) cell lines treated with 10Gy IR.

G) Alkaline phosphatase (AP) staining and reprogramming efficiency quantification. The number of AP positive colonies is shown as a ratio to wild type. Analysis by one-way ANOVA from biological replicates. wt ctrl n = 3, AABB n = 4, BBCC n = 4, AACC n = 3, AABBCC n = 4.

**Figure Legend Snippet:**( A – D ) TDP1 −/− MEFs complemented with EV or FLAG-TDP1 variants (TDP1 −/−/WT and TDP1 −/−/S61A ) were treated with or without CPT (15 nM; 24 h) or Aph (0.4 μM, 24 h) alone or in combination (CPT + APH 24 h) and enriched at M-phase. Representative images show break-induced repair with newly synthesized mitotic DNA marked by BrdU foci (red). The γH2AX foci, signifying the DNA strand breaks, are shown in green.

Anti-HH3 and anti-pHH3 were used as chromosomal and mitotic markers.

**Article Title: **Neuronal DNA repair reveals strategies to influence CRISPR editing outcomes

**Journal: **bioRxiv

**doi: **10.1101/2024.06.25.600517

**Figure Legend Snippet:**a) Schematic: Genome editing proteins can perturb DNA, but cellular DNA repair determines the editing outcome. b) Timeline of differentiating iPSCs (blue) into neurons (green). After at least 2 weeks of differentiation/maturation, postmitotic neurons are treated with VLPs delivering Cas9 protein (yellow) and sgRNA (orange). c) Cas9 VLPs induce DSBs in human iPSC-derived neurons. Representative ICC images of neurons 3 days post-transduction with B2Mg1 VLPs, and age-matched untransduced neurons. Scale bar is 20 µm. Arrows denote examples of DSB foci: yellow puncta co-labeled by γH2AX (red) and 53BP1 (green). Dose: 1 µL FMLV VLP per 100 µL media. d) Genome editing outcomes differ between iPSCs and isogenic neurons. CRISPResso2 analysis of amplicon-NGS, from cells 4 days post-transduction with B2Mg1 VLPs. Dose: 2 µL FMLV VLP per 100 µL media. Data are averaged across 3-6 replicates per cell type, and expressed as a percentage of total reads. Thick blue background bars are from iPSCs; thin green foreground bars are from neurons.

**Techniques Used: **Derivative Assay, Transduction, Labeling, Amplification

**Figure Legend Snippet:**a) Unmerged panels from , showing DSBs induced by Cas9-VLPs in human iPSC-derived neurons, compared to age-matched untransduced neurons. For a-b: Neurons transduced 2 weeks into differentiation, and imaged 3 days post-transduction. DSBs are co-labeled by markers γH2AX (red) and 53BP1 (green). Dose: 1 µL FMLV VLP per 100 µL media. Scale bar is 20 µm. b) Additional representative ICC images showing DSBs induced by Cas9-VLPs in human iPSC-derived neurons, compared to age-matched untransduced neurons.

**Techniques Used: **Derivative Assay, Transduction, Labeling

**Figure Legend Snippet:**a-c) DSB repair markers over time in untransduced (a), B2Mg1-transduced (b), and NEFLg1-transduced (c) neurons. DSBs are co-labeled by ICC markers γH2AX (red) and 53BP1 (green). Dose: 1 µL FMLV VLP per 100 µL media. Neurons were fixed at 1,4, or 7 days post-transduction as labeled. One representative image from each condition is shown. Transduction was 2 weeks into differentiation. Scale bar is 20 µm. Same experiment as , but now showing unmerged panels individually, and including additional conditions (timepoints, sgRNAs). Therefore, the merged panels for untransduced and B2Mg1-transduced at 1 day and 7 days are the same as in , but uncropped here.

**Techniques Used: **Labeling, Transduction

**Figure Legend Snippet:**a) ChIP-qPCR for γH2AX binding at various distances from the cut site over time. Same conditions as , but with γH2AX antibody instead of Mre11. b) Schematic illustrating our strategy to detect cut-and-resealed loci by using a ChIP-qPCR amplicon that spans across the cut site. Repair protein binding suggests that the locus had been cut, and successful PCR amplification suggests that the cut has since been resealed. Note: however, it remains ambiguous whether these loci were sealed with or without an indel. c-d) Some loci have been resealed as early as 2 days post-transduction. ChIP-qPCR using the spanning amplicon to detect cut-and-resealed loci, with both Mre11 (c) and gH2AX (d). Same procedures as and S9a, but using different amplicons (cut site spanning, and different chromosome control). e) Cas9 protein in iPSCs gets quickly diluted and/or degraded to background levels within 2 days post-transduction; therefore, these neuron ChIP-qPCR data cannot be compared to iPSCs. Pulse-chase to track degradation of Halo-tagged Cas9 in iPSCs. First, iPSCs (with/without lentivirally integrated Halo-Cas9 and B2Mg1) were seeded onto glass-bottom 96-well plates with ∼2,000 cells per well. iPSCs were pulsed with 40 µM fluorescent Halo ligand (Promega HaloTag-JF549, cat. #GA1110) for 1 hour, then washed with fresh media 3 times to prevent newly translated Cas9 protein from being labeled. iPSCs were then chased with 2 µM of an unlabeled Halo ligand (Promega ent-HaloPROTAC3, cat. #GA4110) as a binding competitor. Nuclei were labeled with NucBlue (ThermoFisher, cat. #R37605) 20 min before live cell imaging on the Image Xpress Confocal Microscope. Halo fluorescence signal was measured at several timepoints to track the degradation/dilution of the pulse-labeled Cas9 molecules over time. Analyzed in CellProfiler. 8 replicate wells; error bars show standard deviation.
